You seem to be quite fond of flax seed... Do you think you
need it for the Omegas?
By the way, I see you like an omega6/3 ratio of four, that is
the same ratio in Italian recommended Omega-6 and Omega-3
intakes (6g / 1,5g), while the US IOM DRIs say 17g/1,6g
(males 19-50ys).

Well, yes, if it's a healthy diet, it should provide most of
the vitamins and minerals you need, generally speaking... but
how easy is it to have a healthy diet?

Yeah... If you *really* need to supplement a vitamin or a
mineral, then supplement it separately and use the good stuff.
If you don't need, just don't bother at all. Right?

Your page says: "My data on food nutrients comes almost
entirely from the United States Department of Agriculture
Nutrient Data Laboratory (USDA)."
Have you considered the vitamin losses in food storage and
cooking, and in industrial foods?

I also read that some vitamins work better in their natural
form, as found in food rather than in pills.
